Reference picture 1, flows the step of show the method for cleaning embodiment of Email attachment in a kind of mobile terminal of the invention
Cheng Tu, specifically may include steps of：
Step 101, synchronization and at least part of mail is preserved from mail server.
In implementing, the embodiment of the present invention can be using in the terminal, for example, mobile phone, panel computer, individual
Digital assistants, wearable device (such as glasses, wrist-watch) etc..
The operating system of these mobile terminals can include Android (Android), IOS, Windows Phone, Windows
Etc..
The operation of Mail Clients can be generally supported in these operating systems, the Mail Clients enters with mail server
Row connection, to receive, send mail.
It should be noted that these Mail Clients can be the client of system intialization, or third-party visitor
Family end, the embodiment of the present invention is not any limitation as to this.
In embodiments of the present invention, enter with mail server when user's Mail Clients in the terminal is operated
Row is synchronous, or, regularly or manually with mail server synchronize (as received mail), etc..
Because the mail protocol between Mail Clients and mail server is different, therefore, synchronous operation also has
Institute is different.
Furthermore, the mail protocol between Mail Clients and mail server includes following one or more：
1st, POP3 (Post Office Protocol 3, the 3rd version of post office protocol)
POP3 agreements allow the mail on Mail Clients download mail server, and storage to local host is (such as mobile whole
End) on, but, in the operation (such as mobile e-mail, mark have been read) of Mail Clients, will not feed back on mail server,
For example, 3 envelope mails during mailbox has been collected by Mail Clients and move to alternative document folder, these on mail server
Mail is without simultaneously mobile.
2nd, SMTP (Simple Mail Transfer Protocol, Simple Mail Transfer protocol)
Smtp protocol is one group of specification for being used to transmit mail from source address to destination address, and mail is controlled by it
Transfer mode.Smtp protocol belong to TCP/IP (Transmission Control Protocol/Internet Protocol,
Transmission control protocol/Internet Protocol) protocol family, it helps every computer (such as mobile terminal) in transmission or middle transfering the letter
Next destination is found during part.
SMTP certifications, are exactly briefly that requirement must can just log in mail clothes after there is provided account name and password
Business device, it is possible to use family avoids being invaded and harassed by spam.
3rd, IMAP (Internet Mail Access Protocol, interactive email access agreement)
IMAP is with one of similar mail access standard agreements of POP3.Unlike, after opening IMAP, in mail client
The mail that end is collected is remained on mail server, while the operation on Mail Clients can all feed back to mail service
On device, such as：Mail is deleted, mark has been read, the mail on mail server can also do corresponding action.So, from browser
Log in mailbox or Mail Clients and log in mailbox, it is seen that mail and state be consistent.
For mail server, for above-mentioned mail protocol, it will usually use following one or more ports：
25：It is used to receive using the mail server of smtp protocol and sends mail, Mail Clients is used to send postal
Part.
110：It is used to receive mail using the Mail Clients of POP agreements.
143：It is used to receive mail using the Mail Clients of IMAP protocol.
465：Using the encryption port of SMTP, for sending mail.
995：Using the encryption port of POP agreements, Mail Clients is used to receive mail.
Certainly, above-mentioned mail protocol is intended only as example, when the embodiment of the present invention is implemented, can be set according to actual conditions
Other mail protocols are put, the embodiment of the present invention is not any limitation as to this.In addition, in addition to above-mentioned mail protocol, art technology
Personnel can also according to actual needs use other mail protocols, and the embodiment of the present invention is not also any limitation as to this.
In embodiments of the present invention, the mail for being preserved in mobile terminal at least partly synchronization and is protected from mail server
Deposit, for example, the mail in synchronous inbox, outbox, it is, however, possible to have need not partly be synchronized from mail server,
For example, draft, the embodiment of the present invention is not any limitation as to this.
Step 102, selection meets the targeted mails of cleaning condition from the mail for preserving.
Mobile terminal with mail server carry out mail it is synchronous after, have some email storages in mobile terminal sheet
Ground.
Using the embodiment of the present invention, cleaning condition, such as the establishment duration of mail, shifting can be pre-set based on some factors
Whether storage information, the affiliated file of mail in dynamic terminal, the browsing time of mail, account setup, mail mark, mail is big
Communication frequency, mail significance level of small and peer user (sender or addressee) etc..
If the mail for detecting mobile terminal preservation meets the cleaning condition, it is targeted mails that can regard the mail,
Carry out cleaning treatment.
In implementing, mobile terminal can start shooting, under the conditions of timing etc., start annex and clear up service automatically
(AttachmentAutoCleanService) services selection, is cleared up by the annex automatically and targeted mails are cleared up.
Step 103, deletion has been downloaded into the annex carried in local, described targeted mails.
In embodiments of the present invention, for meeting the targeted mails of cleaning condition, if carrying annex in the targeted mails
And it is local to have been downloaded into mobile terminal, then can delete be downloaded to local annex in the targeted mails.
It should be noted that annex is by the file of mail transmission, including audio file, video file, document, compression
File, etc..
In android system, the data of mail are stored in special mail database, such as SQL (Structured
Query Language, SQL) database, the mail data library storage is local in mobile terminal, such as/data/
Data/com.android.email/ files.
In a step 102, the Cursor (verniers of the targeted mails for meeting cleaning condition can be inquired about in mail database
Interface), the content of the respective field of mail in mail database, such as mail ID can be got by the Cursor
(MessageId), the account ID (AccountId) of affiliated account, annex ID (_ id) etc..
In step 103, targeted mails can be found (with MessageId in mail database by the Cursor
Represent) annex, be deleted.
Wherein, the store path of annex is：
<database-path>/account#.db_att/item#
Wherein, account# represents that account ID, item# represent annex ID.
For example, the mail of MessageId=5119 is targeted mails, the targeted mails belong to account " 10 ", the ID of annex
Respectively 6030,6031,6032,6033, its storage address is respectively：
/data/data/com.android.email/databases/10.db_att/6030
/data/data/com.android.email/databases/10.db_att/6031
/data/data/com.android.email/databases/10.db_att/6032
/data/data/com.android.email/databases/10.db_att/6033
After these document alignments are arrived, you can (* .db_att are the files of annex storage to enter 10.db_att files
Folder, * is asterisk wildcard) delete file 6030,6031,6032,6033.
The embodiment of the present invention is synchronous with mail server in the terminal and preserves at least part of mail, in mobile terminal
Some mails are locally stored, selection meets the targeted mails of cleaning condition in these mails for preserving, and have deleted its carrying
And be downloaded to local annex, realize the automatic cleaning of Email attachment, release the memory space of mobile terminal, this
A little targeted mails being cleaned, still exist in original file, are not deleted locally from mobile terminal, in mobile terminal
Mail after cleaning retains the contents such as text, can be carried out in mobile terminal with normal browsing, also, the cleaning of mail,
Former mail on mail server is unaffected, and annex is deleted not in mail server, and annex is deleted in the terminal
Can still be downloaded from mail server afterwards, recovered, it is ensured that the normal of mail is used.
Reference picture 2, the step of show the method for cleaning embodiment of Email attachment in another mobile terminal of the invention
Flow chart, specifically may include steps of：
Step 201, synchronization and at least part of mail is preserved from mail server.
Step 202, inquires about the creation time of the mail for preserving.
In embodiments of the present invention, creation time can be the time for creating the mail in the terminal.
For example, user A on November 20th, 2016 to user B send a mail, the email storage in mail server,
User A opened Mail Clients on November 21st, 2016, and the mail synchronous with mail server downloads to guarantor in mobile terminal
Deposit, the creation time of the mail is on November 21st, 2016.
Step 203, the very first time calculated between the creation time and current time is poor.
Current time can be the time that mobile terminal is currently provided, or, the time that clock server is currently provided, this
Inventive embodiments are not any limitation as to this.
Because creation time is prior to current time, therefore, current time subtracts creation time, then can obtain the very first time
Difference, represents the establishment duration of mail.
Step 204, sets first time period.
Step 205, by very first time difference more than the mail of the first time period, is set to targeted mails.
Step 206, deletion has been downloaded into the annex carried in local, described targeted mails.
If the establishment duration of mail is more than first time period, then it represents that the mail creation duration is more long, no longer effective property
Possibility it is larger, the probability that user browses is smaller, meets cleaning condition, therefore, it can for the mail to be set to targeted mails.
In an example of the embodiment of the present invention, the occupancy of local storage space can be detected, wherein, the storage is empty
Between can include memory headroom, disk space.
Judge occupancy whether more than default occupancy threshold value.
If, then it represents that memory space occupancy is more, and storage resource is more not enough, in order to discharge more storage resources,
Very first time value can be selected to be set to first time period, as a example by 3 days, that is, the mail created before selecting 3 days is used as target postal
Part is cleared up.
If not, then it represents that memory space occupancy is less, and storage resource is more sufficient, in order to preserve the complete of more mails
Property, the second time value can be selected to be set to first time period, as a example by 30 days, that is, the mail created before selecting 30 days is used as mesh
Mark mail is cleared up.
Certainly, in addition to the time value of first time period is set according to the occupancy of memory space, it can also be used
His mode sets the time value of first time period, for example, one time value of acquiescence, etc., the embodiment of the present invention is not subject to this
Limitation.
In implementing, radio receiver can be created, if listening to the low broadcast of memory space (such as internal memory),
Represent that occupancy is more than occupancy threshold value, otherwise, it is believed that occupancy is less than or equal to occupancy threshold value.

Comprise the following steps：
Step 401, inquires about the browsing time of the mail for preserving.
Step 402, calculates the second time difference between the browsing time and current time.
Whether step 403, judge second time difference in default second time period；If so, then performing step
404, if it is not, then performing step 405.
Step 404, forbids for the mail being set to targeted mails.
Step 405, it is allowed to which the mail is set to targeted mails.
In embodiments of the present invention, whether the browsing time that can be based on mail verifies to mail, judges the mail
Allow to be set to targeted mails.
Specifically, user can be recorded in mail database for the operation of mail, such as opened, close, marked
Deng can be read in mail database the browsing time of mail, the generally the last time opened.
If the second time difference between browsing time and current time in second time period (such as 1 day), represents the postal
Browsed by user in the part nearer time, the probability that user browses the mail again in the recent period is higher, forbids being set to targeted mails
Cleared up.
, whereas if the second time difference between browsing time and current time exceedes in second time period (such as 1 day), table
Show in the mail nearer time and do not browsed by user, the probability that user browses the mail again in the recent period is relatively low, it is allowed to be set to
Targeted mails are cleared up.
Reference picture 5, shows the example flow diagram of another selection target mail of one embodiment of the invention, specifically may be used
